Carbondale micro hydro project cruising to approval — @AspenJournalism

Micro-hydroelectric plant

From Aspen Journalism (Brent Gardner-Smith) via The Glenwood Springs Post-Independent:

On March 9 the town of Carbondale notified the Federal Energy Regulatory Commission it plans to install a micro hydropower turbine in a pipe leading to its municipal water treatment plant on Nettle Creek.

On March 13 FERC found that Carbondale’s project qualified for a quick review under the Hydropower Regulatory Efficiency Act of 2013, which streamlined the permitting process for hydro projects of less than 5 megawatts.

And by April 27, if no one claims the project doesn’t qualify, the town can expect to get a letter from FERC saying the town does not need a license and can go ahead, at least as far is FERC is concerned.

At 28 kilowatts, Carbondale’s project is much smaller than the 5-megawatt limit in the efficiency act, it’s a new license using a nonfederal pipeline, and it complies with the Federal Power Act.

So far, FERC’s fine with it, and it’s received no objections from the public.

The project involves installing a “turbine/generating unit” in an existing 10-inch municipal pipeline, or “raw water intake line.”

The pipe is 1,800 feet long and transports about 1 cubic foot per second of water downhill from Nettle Creek to the city’s treatment plant. The plant is eight miles up the Crystal River valley on the lower slope of Mount Sopris.

The turbine would be built inside a vault installed in the pipeline, near the treatment plant. A short bypass system would allow water to be moved around the turbine for repairs and maintenance.

“It’s taking advantage of the water that is already going down that pipeline,” said Mark O’Meara, Carbondale’s utilities director. “We’re not going to increase it. We’re not going to be doing any additional diversion.”

O’Meara also said that since it’s a nonconsumptive use of water already running down a pipeline, the town did not have to change its existing municipal water rights to specifically add hydro as a use.

The turbine’s “installed capacity” of 28 kilowatts and its “estimated annual generating capacity” of 190,000 kilowatt-hours is about enough electricity to offset the amount of power used to run the water plant, O’Meara said.

According to Craig Cano, a media relations officer at FERC, the 28 kilowatt figure refers to how much power the turbine could produce at any moment.

“That’s real small,” Cano said, pointing out it’s 0.028 of a megawatt, while a typical baseload-generating power plant’s capacity is in the hundreds of megawatts.

The 190,000 kilowatt-hour figure refers to the total amount of energy produced over a year.

The resulting electricity would either be sent through the existing Holy Cross Energy system that today powers the plant, or perhaps be used directly in the plant, O’Meara said. The town would get credit from Holy Cross for hydropower sent out over the grid.

The project has been in the works since the 1990s, but it still has a long way to go.

On the list is an in-depth feasibility study considering design, engineering and cost. A 2012 estimate from engineering firm SGM put the cost at $180,000. O’Meara did not have an updated cost.

And since the water plant and pipeline are on U.S. Forest Service land, the agency also has jurisdiction over the project.

But O’Meara said after going to a recent workshop put on by the Colorado Energy Office, it seemed like the right time for the town to enter the streamlined FERC process and see how it goes.

It took only four days after receiving Carbondale’s “notice of intent” for FERC to issue its “notice of preliminary determination” that the project qualified for speedy review.

That notice, along with town’s initial notice, are on town’s website, on its utilities page.

Also on March 13, FERC opened two windows for parties to contest the qualifications of the project.

The first was a 30-day window to file a motion to intervene. By April 12, no one had.

The second was a 45-day window for less formal but still “contesting” comments to be made.

That window closes April 27, and as of April 13, FERC had received no comments.

“If no party contests staff’s initial determination that the project meets the criteria for a qualifying conduit hydropower facility within the 45-day public notice period,” FERC’s Cano said, “the facility is deemed to meet the criteria and FERC staff shortly thereafter will issue a letter notifying the filer that is project has met the criteria.”

If someone does file a comment contesting the project’s qualifications, FERC is supposed to then “promptly issue a written determination as to whether the facility meets the criteria,” Cano said.

Carbondale’s O’Meara said that as far as he knows, no one over the years has raised concerns about the project directly to the town.

@Northern_Water 2017 quota set at 80%

Map of the Colorado-Big Thompson Project via Northern Water

Here’s the release from Northern Water:

Northern Water’s Board increased the Colorado-Big Thompson Project quota allocation to 80 percent at its April 13 Board meeting. With many farmers concerned about the lack of recent moisture and the hope that cities may be willing to provide some rental water to help the region’s agricultural economy, the Board chose to make available an additional 30 percent as supplemental quota for 2017.

The approval increased available C-BT water supplies by 93,000 acre-feet, from the initial 50 percent quota made available last November.

The Board considered snowpack totals, streamflow runoff projections and input from farmers and municipal and industrial water providers in setting the quota. C-BT supplements other sources of water for 33 cities and towns, 120 agricultural irrigation companies, various industries and other water users within Northern Water’s 1.6 million-acre service area.

Directors considered the general dearth of moisture in March as they discussed the quota options. March precipitation was 27 percent below normal and contributed to the Board’s decision to raise the quota.

“It’s dry, it really is,” said Board President Mike Applegate. “The C-BT Project was created to provide a supplemental supply and we have the reserves to do that.”

He echoed the Board’s consensus in making its 61st annual C-BT quota. “Let’s make the water available now so our allottees can make their plans.”

Directors base their decision on the region’s need for supplemental water, while balancing project operations and maintaining water in storage for future dry years.

By a comfortable 68-31 margin, the U.S. Senate today confirmed President Trump’s nominee for Secretary of the Interior, Ryan Zinke.

The former Montana member of Congress will head a department that manages around 500 million acres of land and waterways in the United States.

Zinke’s department also includes the federal Bureau of Reclamation, the agency responsible for the system of dams and reservoirs on the Colorado River, the waterway that is integral to the livelihood of 40 million U.S. citizens living in the Southwest.

In a statement declaring his approval of the appointment, Arizona Sen. Jeff Flake said he looked forward to working with Zinke’s department, notably on behalf of Arizona’s Colorado River allotment.

Pueblo Dam hydropower plant should be online next year

From KOAA.com (Andy Koen):

The Pueblo Dam will soon be producing enough renewable energy to power 3,000 homes. The Southeastern Colorado Water Conservancy District plans to begin construction of the $19.5 million hydroelectric generating station later this year. The construction site will be located downstream form the Pueblo Dam River Outlet which was constructed to serve as the connection for the Colorado Springs Utilities Southern Delivery System.

“We’ll be using the water that’s flowing into the river again, we won’t be consuming any of that water,” explained Conservancy District spokesman Chris Woodka.

The District borrowed $17 million from the Colorado Water Conservation Board to build the plant. It will house a trio of turbines, each capable of producing electricity whether the river is moving fast or slow.

“We designed it so that it would at several different flows so that we could get the maximum production out of it,” Woodka said.

With a rating of 7.5 megawatts, the plant will create enough power for roughly 3,000 homes. It’s the kind of clean power that City leaders in Pueblo want for their community…

The Conservancy District expects to generate around $1.4 million annually from the sale of it’s electricity. Groundbreaking is expected to take place in May and Woodka said their goal is to have the power plant go online in the Spring of 2018.

Inside the Stagecoach Dam: Harnessing the Power — Steamboat Today

Here’s a report from a tour of Stagecoach Dam from Matt Stensland writing for Steamboat Today. Click through for the cool photo of the drain system from inside the dam. Here’s an excerpt:

It is a careful balancing act at the Stagecoach Dam, where electricity is generated for homes, fish habitat is managed and water is stored for a time when cities, ranchers and industry need it.

Behind the steel door, mineralized sludge covers the concrete walls and incandescent bulbs dimly light the narrow corridor.

These are the guts of the Stagecoach Dam southeast of Steamboat Springs, and it can be a little unnerving knowing that at the other side of the wall, 9,360 pounds of pressure push against each square foot of concrete.

Water drips from the ceiling and falls from drain pipes that collect water from the seeping concrete.

“All dams get water into them,” said Kevin McBride, adding that not having a system to drain the water would create pressure and put the dam’s integrity at risk…

“It’s pretty much paradise here,” said Blankenship, who most recently worked at a coal mine and previously worked in the power house of the USS Enterprise for the U.S. Navy.

Rogers has an electrical engineering degree from the Colorado School of Mines.

In addition to monitoring the integrity of the dam, they oversee the hydroelectric power plant, which was named the John Fetcher Power Plant in 1997. He pushed to make electricity generation part of the dam design.

“I think John was a natural conservationist and to have this capability in a project that size and not do it was a bad thing,” said McBride, referring to Fetcher, who died in 2009 at age 97 after being recognized as one of the state’s water leaders.

Above the loud turbine in the power house sits a sign warning people not to stand underneath. That is because above, there is a large, weighted steel lever that will come crashing down if the power generated at the plant needs to immediately come off the grid.

On Tuesday afternoon, the electrical turbine was generating upwards of 500 kilowatts. The system can generate as much as 800 kilowatts, but generation is limited by the amount of water that is flowing into the reservoir.

“The generation, it fluctuates wildly,” said Andi Rossi, the water district’s engineer. “If the flows get too low, we shut down for power generation. In a big wet year, we’ll make a lot of power.”

The water district had been selling the power to Xcel Energy, but Yampa Valley Electric Association began buying the power last year for six cents per kilowatt hour. In 2016, YVEA paid more than $230,000 for the 3.85 million kilowatt hours generated at the dam. That is enough energy to power about 355 homes.

Power generation varies and is dependent on runoff. During the drought year of 2002, only 1.85 million kilowatt hours was produced. When there was abundant snowfall in 2011, 4.7 million kilowatt hours was produced. Since 1999, an average of 3.8 million kilowatt hours has been made each year…

A tower of concrete in the reservoir beside the dam has three gates that allow different temperatures of water to be mixed and sent through a pipe under the dam toward the generator.

From there, the water is either sent through the generator or through a pipe called a jet flow, which shoots water out of the power plant and helps oxygenate the water for fish habitat in the section of river in front of the dam known as the tailwaters.

The area is an angler’s delight and can only be accessed by snowmobile from the Catamount area or by hiking along a county road from Stagecoach State Park.

“It’s phenomenal,” Colorado Park and Wildlife fish biologist Billy Atkinson said.

With improvements by Parks and Wildlife to the river habitat, the area has thrived for fishing, partly because of the dam and reservoir. Relatively warm water released from the dam keeps the section of river from freezing over, and the water from the reservoir is rich in nutrients for the fish.

“The system is very productive,” Atkinson said.

In 2016, 25 percent more people visited the section of river, and 4,000 trout were measured per mile.

Not all tailwaters below dams in Colorado are experiencing similar success.

“It depends on the dam and the operations of the dam,” Atkinson said.

Loveland: Solar to replace hydro from damaged Idylwilde dam

From TheDenverChannel.com (Kurt Sevits):

The city of Loveland has finished work on a large-scale solar power installation that aims to replace the damaged Idylwilde hydroelectric dam.

The dam, built in 1917, was badly damaged in the Sept. 2013 floods that devastated the Front Range corridor.

Loveland received about $9 million in disaster recovery funds from the Federal Emergency Management Agency to construct the new Foothills Solar and Substation project, which the city says is capable of producing more power than the dam.

The Idylwilde Dam’s hydroelectric facility was capable of producing 900 kilowatts of electricity before it was removed. The new solar project, on the other hand, has a capacity of 3.5 megawatts, more than tripling the output of the dam.

City officials said the solar project is expected to produce about 6,813 megawatt hours of electricity each year — enough to power about 574 homes.

To produce as much power as possible, the array uses solar tracking technology, which allows the panels to move throughout the day so they’re always facing the sun.

Boulder-based Namaste Solar designed and built the solar array.

The city said the project is the first energy-producing facility to receive approval through FEMA’s “Alternate Project” program, which permits the use of federal money for new construction when restoring a damaged building isn’t considered to be in the public interest.

$5.1 million of the FEMA funds were used to build the solar array. The remainder will be used to construct an electric substation on the site. It’s expected to be completed in the spring.

@Colorado_TU: Lessons of the battle over the Roan Plateau

Oil and gas development on the Roan via Airphotona

Here’s guest column from David Nickum writing in the Grand Junction Daily Sentinel:

For more than a decade, the battle over Colorado’s Roan Plateau — a beautiful green oasis surrounded by oil and gas development — raged in meetings and in courtrooms. At issue: Would the “drill, baby, drill” approach to public lands carry the day and the path of unrestrained energy development run over one of Colorado’s most valuable wildlife areas? Or would “lock it up” advocates preclude all development of the Roan’s major natural gas reserves?

Luckily, this story has a happy ending — and a lesson for Colorado and other states in the West struggling with how to balance the need for energy development with conservation of public lands and irreplaceable natural resources.

The Bureau of Land Management recently issued its final plan for the Roan Plateau, closing the most valuable habitat on top of the plateau to oil and gas leases. The plan, which will guide management of the area for the next 20 years, also acknowledges the importance of wildlife habitat corridors connecting to winter range at the base of the plateau.

At the same time, the BLM management plan allows responsible development to proceed in less-sensitive areas of the plateau that harbor promising natural gas reserves and can help meet our domestic energy needs.

What happened? After years of acrimony and lawsuits, stakeholders on all side of the issue sat down and hammered out a balanced solution. Everyone won. It’s too bad it took lawsuits and years of impasse to get all sides to do what they could have done early on: Listen to each other. We all could have saved a lot of time, money and tears.

The Roan example is a lesson to remember, as the incoming administration looks at how to tackle the issue of energy development on public lands. There’s a better way, and it’s working in Colorado.

The BLM also this month, incorporating stakeholder input, closed oil and gas leasing in several critical habitat areas in the Thompson Divide — another Colorado last best place — while permitting leasing to go ahead in adjacent areas.

That plan also represents an acknowledgment that some places are too special to drill, while others can be an important part of meeting our energy needs.

And in the South Park area — a vast recreational playground for the Front Range and an important source of drinking water for Denver and the Front Range — the BLM is moving ahead with a Master Leasing Plan (MLP) for the area that would identify, from the outset, both those places and natural resources that need to be protected and the best places for energy leasing to proceed.

We have said that we want federal agencies in charge of public lands to involve local and state stakeholders more closely in land management planning — that perceived disconnect has been the source of criticism and conflict in the West regarding federal oversight of public lands.

The MLP process is a new tool that promises to address some of that top-down, fragmented approach to public land management. To their credit, the BLM is listening and incorporating suggestions from local ranchers, conservation groups and elected officials into their leasing plan for South Park.

This landscape level, “smart from the start” approach is one way for stakeholders to find consensus on commonsense, balanced solutions that allow careful, responsible energy development to occur while protecting our most valuable natural resources.

The lesson I take from the Roan? We can find solutions through respectful dialogue—and we shouldn’t wait for litigation to do so. [ed. emphasis mine] Coloradoans can meet our needs for energy development and for preserving healthy rivers and lands by talking earlier to each other and looking for common ground.
